摘要： One exemplary embodiment can be a system for separating a plurality of naphtha components. The system can include a column, an overhead condenser, and a side condenser. Generally, the column includes a dividing imperforate wall with one surface facing a feed and another surface facing at least one side stream. Typically, the wall extends a significant portion of the column height to divide the portion into at least two substantially vertical, parallel contacting sections. Typically, the overhead condenser receives an overhead stream including a light naphtha from the column. Usually, a side condenser receives a process stream from the column and returns the stream to the column to facilitate separation. A cooling stream may pass through the overhead condenser and then the side condenser.

摘要： The selective saturation of unsaturated aliphatic hydrocarbons (e.g., diolefins) in a hydrogenation feed stream comprising an aromatic compound (e.g., benzene) and one or more nitrogen compounds renders it beneficial when the stream or a portion thereof is subsequently treated (e.g., with a zeolitic adsorbent) to remove nitrogen. In particular, the selective saturation of, for example, olefins and diolefins prolongs the life of the nitrogen guard bed. In a representative embodiment, the selective hydrogenation is applied to a recycle benzene-containing stream recovered in the separation section (e.g., from the benzene/toluene splitter overhead) of a styrene production process, prior to treatment with a nitrogen guard bed adsorbent.

摘要： Methods are disclosed for the dehydrogenation of feed streams, such as in the manufacture of styrene from ethylbenzene, using a catalyst bed having catalyst with differing activities. In particular, the use of upstream and downstream catalyst beds of relatively low and high activities, respectively, can reduce the production of unwanted byproducts, especially in styrene production processes employing an oxidative reheat step (oxidation zone) prior to ethylbenzene dehydrogenation. The methods allow the maximum temperature in the oxidation zone to be decreased, thereby reducing the formation of unwanted oxygenated byproducts (e.g., phenol).
